The Cyclostomata are the modified and degenerate offshoot of the primitive vertebrate stalk. Due to their circular mouth, they are named Cyclostomata. They are parasitic, usually feeding on fish in their adult stage. Morphologically, they resemble eels. They are known to be the only living vertebrates without true jaws, hence called Agnatha.

The Late Ordovician mass extinction (LOME), sometimes known as the end-Ordovician mass extinction or the Ordovician-Silurian extinction, is the first of the "big five" major mass extinction events in Earth's history, occurring roughly 443 Mya.

Some zoo-ids are made to perform special tasks. 3) Chordata Characteristics: a) They have a dorsal, hollow nerve cord. b) They have gill slits c) They have a notochord COOL FACT! They have multiple identities. 4) AnnelidaBryozoans are a classic "wild card" taxa, jumping around in otherwise stable phylogenies. They seem to be closer to Trochozoa than to Ecdysozoa or Deuterostomia in most molecular analyses. Alas, the bryozoan genome is as derived as its morphology, making it a difficult subject for molecular methods. Amathia verticillata is an erect, soft-bodied bryozoan, first described from the Mediterranean Sea and now widespread in tropical, subtropical, and warm-temperate waters around the world.

Thin plates of crust moved constantly over the softer ...Bryozoa. : Life History and Ecology. Bryozoans can reproduce both sexually and asexually. Asexual reproduction occurs by budding off new zooids as the colony grows, and is this the main way by which a colony expands in size. If a piece of a bryozoan colony breaks off, the piece can continue to grow and will form a new colony.
